No he didn't. The Feds aren't charging him with anything, and the state won't charge him with anything serious, i.e., anything that requires criminal intent as an element. You really don't know the full meaning of the words "serious crime".
That is true; I do not know the legal definition of "serious crime," and I did not mean to imply any legal definitions.
I meant that the crime of running past security to avoid it was not simply an innocent mistake, and that it could have had serious consequences. His not being charged with a crime does not mean that he didn't commit crimes. Perhaps the prosecutors simply did not want to make a case out of the crimes for which they did not accuse him.
